Concrete shell thickness with Karamba

Hello,

I just started working with Karamba.
I am currently working on a concrete shell. The material that Karamba provides me is quite thick and I would like it to be much thinner! Is there any way I can change and optimise the thickness?
Or is the problem in finding the shape with grasshopper / kangaroo?

Many thanks in advance.

Hi, you can use the Cross Section component to set the thickness of a shell. See 3.3.2: Shell Cross Sections - Karamba3D 2.2.0 for further information
